Description
During winter most of the Norrbysjön lake is covered in ice, but where Motala ström meets Norrbysjön the water is ususally open year round. During this period large flocks of (Κοινή) Φαλαρίδα, Χηνοπρίστης, Πρασινοκέφαλη Πάπια, Μαυροκέφαλη Πάπια, (Βουβός) Κύκνος, Canada Goose, Ασημόγλαρος του Βορά and (Ευρωπαϊκή) Βουκεφάλα can be found. Often numbering in the hundreds. Within these flocks rarer wintering birds like Σκουφοβουτηχτάρι, (Ευρωπαϊκή) Καλημάνα, Αγριόκυκνος, dabbling ducks, (Κοκκινόλαιμο) Νανοβουτηχτάρι , Ασπρομέτωπη Χήνα, (Ευρωπαϊκό) Ψαρόνι, Γκισάρι, and (Ευρωπαϊκός) Κορμοράνος can be spotted. The large amounts of wintering birds attract birds of prey like (Ευρωπαϊκός) Θαλασσαετός, (Κοινή) Γερακίνα, and Χειμωνόκιρκος.
When the ice melts large amounts of pipits, larks, geese, Αγριόκυκνος, and sometimes Νανόκυκνος, use the fields around the lake as feeding grounds. The lake is usually filled with many dabbling ducks, gulls and terns. Husbyängarna are often flodded, and usually hold wading birds like Κουφομπεκάτσινο, Κοκκινοσκέλης, Αμμοσφυριχτής, (Ευρωπαϊκή) Καλημάνα, and Πρασινοσκέλης. The reedbeds around the lake are now filled with birds. Some rare birds who are sometimes found around the lakes are (Ευρασιατικός) Ήταυρος, Καλαμοτριλιστής, Μουστακαλής and Τσιχλοποταμίδα. Some rare terns and gulls like Νανόγλαρος and Μαυρογλάρονο pass the lake during the spring migration.
Some rarer breeding birds at the lake are Τσιχλοποταμίδα, (Ευρασιατικός) Ήταυρος, Καμπίσια Πέρδικα, Νανοδρυοκολάπτης, Ορτυκομάνα and (Ευρωπαϊκή) Αλκυόνη. Norrbysjön is and excellent area for night active birds. Around the lake Ορτυκομάνα, (Κοινό) Ορτύκι, Θαμνοτριλιστής, Τσιχλαηδόνι, Ποταμοτριλιστής, Βαλτοποταμίδα can often be heard at the lake.
During autumn large amounts of geese start to visit the lake again. Many more passerine birds can be found on the fields. Among these Χιονοτσίχλονο, Lapland Bunting and Κοκκινοκελάδα are often found. Hundreds of (Ευρωπαϊκό) Βροχοπούλι can often be found on the fields. Sometimes marine ducks like (Ευρωπαϊκή) Μαυρόπαπια and Βελουδόπαπια stay at the lake.
